The HUBEN K1 SPECIAL EDITION has the exact mechanism and performance as the famous K1 with black synthetic stock. However, this Special Edition has the following new features:
- First, the shroud is made with a high-quality carbon fiber tube. And second, it comes with a brand new wooden stock. These upgrades make the Huben K1 lighter and give it a more refined look.
- The Huben K1 is, without doubt, the most powerful semi-automatic bullpup on the market. A marvel of engineering and technology, its patented hammerless platform makes the K1 very different from any other PCP. It is able to achieve a very high rate of fire making the most out of its high capacity 17/19 round mag. The hammerless system is 100% mechanical and provides numerous advantages: high efficiency, zero vibrations, accuracy, and a wide variable power range.
- The Huben K1 was originally designed to shoot accurately at extreme power levels, with long-range shooting and hunting in mind. However, the last version of the K1 has become a more flexible design, becoming an accurate gun at any power level. SUB-MOA at 100 meters.
- Huben K1’s parts have always been made with top quality materials; nonetheless, since 2020 we have pushed our quality control to more demanding standards, guaranteeing excellent results.
